I would find a way to put it on right before. Have the MC inform you that the garter toss will be in 5 minutes and take your Maid/Matron of Honor to the bathroom with you to help slip it on. That way you don’t have it showing throughout the whole evening.

I had to have mine RIGHT above my knee. I couldn’t wear it during dinner because in that spot it was not tight enough to stay up, so I told the DJ to let me know when we were going to be getting started with that sort of stuff. I ran to the bathroom and put it on just before 🙂 And I warned Darling Husband about it as well, so he knew he wasn’t going to be able to get “all up in there”, but it worked out just fine in the end.
